PROPELLER ATTACHMENT Original Filed March 24, 1931 5 Sheets-Sheet 2 v I Inventor 7 .27. Wallace A florney Aug. 30,1932. F. E. WALLACE PROPELLER ATTACHMENT Original Filed March 24. 1931 3 Sheets-Sheet 5 Patented Aug. 30, 1932 UNITED STATES FRIEND E. WALLACE, OF STOCKPOBT, OHIO PROPELLER ATTACHMENT Application filed March 24, 1931, Serial 10.524382. Renewed April 20, 1932;

The present invention relates to an attachment for a propeller and has for its prime object to provide means for preventing the loss of the propeller should the same become detached from its shaft. 7

Another important object of the invention resides in the provision of an attachment of this nature which is simple in its construction, inexpensive to manufacture and install, thoroughly efiicient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of the attachment embodying the features of my invention showing the same installed.

Figure 2 is a detail sectional view through thecone and hub of a propeller.

Figure 3 is an end elevation thereof.

Figure 4 is a perspective view of the rod.

Figure 5 is a perspective view of the pin.

Figure 6 is a sectional view through the tube.

Figure 7 is a plan view thereof. 7

Figure 8 is a sectional view through the cone, and

Figure 9 is an end view thereof.

Referring to the drawings in detail it will be seen that numeral 5 denotes a cone, the larger end of which is adapted to be disposed over propeller hub 6 and engaged therewith by means of screws 7 or like fastening elements. 7

The hub 5 may be slotted as is indicated in Figures 1, 2 and 3 or not slotted as is indicated in Figures 8 and 9.

An L-shaped rod 8 has its short arm 9 extending through an opening 10 in-the apex of the cone 5 and terminating interiorly of'the cone in a ball 11 larger in diameter than the diameter of the opening 10. p

A sleeve 12 is mounted with its lower end threaded in a bracket 14 which supports bearing 15 of the rudder and extends up through an opening in the bottom of the bolt terminating at its upper end in an annular outwardly directed flange 16 which is secured to the bolt by means of screws 17 or any other suitable means. The long arm of the rod ex- '85 tends up through this sleeve and terminates in an eye 18 so that a chain 19 may be engaged therewith and this chain is anchored as at 20 in) any desired or convenient portion of the at. through an opening in the long arm of the rod adjacent the eye 18 to rest on the flange 16. From the above detailed description it will be seen that the cone 5 rotates with the propeller and should the propeller come off the V shaft for any cause whatsoever this rod 8 will prevent the loss of the propeller.

It is thought that the construction, utility and advantages will now be quite apparent to those skilled in the art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed. or sacrificing any of its advantages.

Having thus described my nvention, what I claim as new is: V I

1. An attachment of the class described comprising a cone, means for securing the cone at its larger end over the hub of a propeller, the apex of the cone being formed with an opening, an L-shaped rod having its smaller arm extending through the opening and terminating interiorly of the cone in a ball larger in diameter than the diameter of the opening.

2. An attachment of the class described comprising a cone, means for securing the cone at its larger end over the hub of a propeller, the apex of the cone being formed with an opening, an L-shaped rod having its A pin 21 is adapted to be extended smaller arm extending through the opening and terminating interiorly of the cone in a ball larger in diameter than the diameter of the opening; a sleeve adapted to be anchored 5 in a boat, the long arm of the rod adapted to be extended through the sleeve and said long arm having an opening in its upper end, and a pin for insertion through said opening in the rod to rest on the upper end of the sleeve. 10 3. An attachment for a propeller comprising a cap fastened to the enter endof: the hub of the propeller, a rod rotatably connected With the cap, and means for anchoring the red to a part of aboat. V V )5 In testimony whereof I afiix my signature.
